How to realize the function of generating WeChat red packet by PHP
This article introduces the relevant knowledge of "how to achieve the function of generating WeChat red packet by PHP". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!
Post the core interface code and fill in the data by yourself, and test the OK with the API.

Rewrite the Wechat API interface under PHP
Supported by WeChat red packet and supported by dynamic parameter interface of JSAPI
